How can I implement custom event handling in my application?

You can implement custom event handling by creating event listeners and dispatching events in your application.

Can you give me an example of how to create an event listener?

Sure! In JavaScript, you can use addEventListener to listen for events on an element. For example: element.addEventListener('click', function() { /* your code */ });.

What about dispatching custom events?

You can dispatch custom events using the CustomEvent constructor. For example: let event = new CustomEvent('myEvent', { detail: { key: 'value' }}); element.dispatchEvent(event);.

How do I handle the custom event once it's dispatched?

You can handle it by adding an event listener for the custom event type. For example: element.addEventListener('myEvent', function(e) { console.log(e.detail); });.
